In my view, the subway is the most efficient transportation in my country. First of all, there are many lines of subway carry people to every part of the country; especially it covers the most important blocks and areas of each city. So it is very convenient for people to take it and go to a lot of place soon. Secondly, the subway number of each line is larger than other transportations. There are even more in rush hours. By taking it, people can go to work very fast and save a lot of time. It is very efficient because it won’t be influenced by the car jam. There are no other cars, bicycles, and buses under the ground! No doubt, subway is the most efficient transportation for daily life. 

The most efficient transportation is the bus service. First of all, thanks to the well developed public transportation, it’s very convenient to take a bus because it is always easy to one stop near you and your destination. In addition, because the road condition in China has improved greatly, the bus can easily run at the speed of 120 km/h. For example you can travel from shanghai to Nanjing in less than 3 hours. Furthermore, it’s very cheap to take a bus as you travel around china, and it allows you the time to appreciate the landscape of china along the way. You may even get acquaintance to several friends with the similar interests and temper.
